- after looking at patch-ao again it was quite clear that the previous
revision broke internal RSA support, fix patch and make one slight
improvement to it.
- improve patch-ao by also adding an option --with-rsaref so that the use
of RSAREF has to be enabled instead of enabling it based on the existance
of librsaref. Thus would allow someone to be able to build a version of
PGP on a system that has librsaref installed already. Quite useful in the
situation of doing automated package building.
